Homework Statement
Contact lenses being manufactured in space are returned in a re-entry capsule to Earth for distribution and sale. If the re-entry velocity is 7.4km/s and the re-entry flight-path angle is 10 degrees, determine the maximum deceleration it will experience and at what altitude? The capsule’s BC is 1000 kg/m^2
Homework Equations
a max = V^2 re-entry b sin y/ 2e
The Attempt at a Solution
a max = 7400m/s^2 (0.000139m^-1 sin(10)) / 2(2.7182)
the answer should be 24.813 , I keep getting a very high number of 9.298x10^10 ... why am I so off?
where .000139m^-1 is the atmospheric scale height and 2.7182 is the base of the natural logarithm.
